Be it known that I, JOHN 'WinirrNsoN, a subject of the King of Great Britain and Ireland, residing at 104. Bolton Road, Bradford, in the county of York, England, have invented new and useful improvements in and Relating to Suspension Means for Carburetors for InternaLCombustion Engines (which I have patented in Great Britain, Patent No. 164:,969, June 25, 1920), of which the following is a specification.

This invention relates to improvements in suspension means for carburetors for internal combustion engines.

It is well known that the change of position due to varying inclination of the en gine or vehicle affects adversely a carburetor which is attached to such engine altering as such inclination does the fuel sup ply giving either more or less as the case may be. This disadvantage has been attempted to be overcome by employing a float chamber of special construction with its axis at right angles to the longitudinal axis of the vehicle, such float chamber being mounted on trunnions and provided with a counter weight to ensure the chamber is maintained by gravity in the desired position. 7

The object of this present invention is to arrange and construct the induction pipe in such wise that any type of carburetor may be attached thereto, either parallel or at right angles to the engine and by gravity or control means be so arranged that the jet may be arranged and maintained in a desired relationship to the level of fuel in the float chamber. In other words with a gravity operated device the carburetor will always swing or rest in a substantially vertical position whatever the inclination of the engine. With a. controlled device the carburetor may be moved out of the vertical in either direction irrespective of the inclination of the engine thus permitting adjustmentto be made during running, the fuel supply being adjusted to meet the requirements of the engine, atmospheric con ditions, or nature of the fuel. In effect the engine becomes independent of the carburetor and the carburetor independent of the engine.

To permit any carburetor to be attached to the device I construct the induction pipe in two portions, one portion being so 1nount ed in respect to the other that it may move, or be moved, either to allow the carburetor attached thereto to assume a vertical position or to be moved at will out of the vertical. in one direction or another.

To those skilled in the art the advantages of such a device, as hereinbefore broadly and hereinafter more particularly specified, will be apparent giving as it does control of supply of fuel, a consequent saving of fuel less changing of gears and added power. Its applications and advantages to aeroplane engines will also be understood.

The invention will be fully understood from the following description when taken in connection with the accompanying drawings and the novel, features thereof will be pointed out and clearly defined in the claims at the close of the specification.

In the drawings Fig. 1. represents a neral elevation of the induction pipe with a carburetor in position. Dotted lines showing inclined positions of the engine.

Fig. 2. represents an elevation showing the two connected portions of the induction pipe.

Fig. 3 represents a sectional elevation of Fig. 2.

Fig. 4- represents a face view of one of the portions of the induction pipe.

5 represents an end view, and

Fig. 6. represents suitable movable connection on the fuel supply pipe to the carburetor.

To carry my invention into effect, I do notinterfere with the carburetor in any way but construct the induction pipe in two parts A. and B. A being the portion to which the part B is attached or suspended. The part A terminates in a flanged face A having a scraped surface and the interior car'ies a boss A by means of radial arms or the like as shown in Fig. i. A bolt C having a cbned or like end C passes through the part. A and boss A such bolt being adjustable as shown, the point C forming one of the points of suspension for the part B. Lugs D are formed on the part A and these lugs carry studs or like D which carry at their other end across plate F which supports the centre bolt F having a coned or pointed end F? which acts as the other part of suspension of the part B.

The part B of the induction pipe is in the form of. a chamber closed at one end and open at the other, the open end having a flanged face B with a scraped surface similar to the face A and a central boss B carrying a bearing 15 for the point C; a bearing B is provided at the closed end for the end F of-- bolt F.

These bearings may be in the form of studs substantially as shown in Fig. 3.

The underside of'the part B will carry a flange such as G which in turn will have connecting means such as studs G (of which there may be two or four) for the carburetor O. This construction enabling the carburetor to be attached either along side or at right angles to the engine.

After adjusting the part B in relation to the part A by means of the suspension or bearing studs (the scraped faces will give the necessary joint between the parts), it will be seen that if the carburetor (attached topart B) is suitablybalanced or controlled, its position may remain vertical whatever the position of the engine, such as to one side or the other as shown by dotted lines in Fig. 1. i 1

There must however be a flexible or controllable connection to the carburetor from the source of supply, this connection may be made in many ways. I have in Fig. 6 shown a known form of double elbow jointed pipe P which will allow of the desired movement. such form is not to scale and in fitting care .must be taken to give a correct arc of move ment, and in Fig. 1 the pipe P is for clearness shown at right angles to its correct position.

'As before mentioned the control may be automatic by weighting the carburetor to cause same to always swing to one position, but this means will not'be always efficient as owing to quality of fuel, weight, atmospheric conditions orthe like adjustment may be required. ThereforeI prefer to be able to control or move the carburetor by hand or mechanical means It will be obvious this may be carried out in many wavs, such for example as a friction band to embrace thecarburetor, which band may be released or moved eitherto free the carburetor or swing it where desired by means of a lever, Bowden wire or the like or a connection may be made to the cranked jointed pipe P to swing the carburetor. These means will be apparent to a person skilled in the art once the arrangement of suspension hereinbefore described is understood and with suitable control devices the supply of fuel may be increased, decreased or shut off at will-adjustment being made as required. Any ordinary carburetor may be employed and the throttle will be operated in the fixed portion A of the induction pipe.

1* or aeroplane work the advantages will be obvious and for motor car work much adjusting, tuning up and the like will be rendered unnecessary. There will be less gear changing and consequently added power and increase in efficiency.

*hat I claim is zl. In a piping systen, a flexible joint, comprising a pair of rigid pipc members having abutting end faces forming a fluid tight joint, one of said members having a pair of journal bearings, and adjustablepivot members carried by the other pipe member for engaging said bearings for maintaining faces in contact while permitting angular movement of one face relatively to the other. i

2. In a piping system, a flexible joint, comprising a pipe member having a joint forming face, a pair of pivot members adjustably supported by said pipe member in opposed coaxial relation, a pipe member having a face adapted to abut the face of saidfirst pipe member thereby to form a fluid-tight joint, and bearings carried by said second pipe member and adapted to be engaged by said pivot members thereby to maintain the faces in contact and permit relative angular movement.

8. In a piping system, a flexible joint, comprising a pair of pipe members having abutting faces forming a fluid-tight joint, each of said members having adjacent to its face an inwardly extending portion pro vided with an opening, each of said members also having an opening remote from said first opening, a plate supported by one of said members and having an opening, all of said openings being in axial alignment. bearings carried by the openings of one of said pipe members, a pivot member threaded into said plate opening and engaging one of said bearings, and a pivot member threaded into the remote opening of the other pipe member and supported for rotation in the inwardly extending portion of said member, said pivot engaging the other bearing thereby to maintain the faces in contact and; permit relative angular movement.
